Immunity test IEC 60601 test level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
See NOTE 2 and NOTE 3
Compliance level Electromagnetic environment – guidance
3 Vrms Portable and mobile RF communications equipment
should be used no closer to any part of the HemoCue
systems, including cables, than the recommended
3 V/m separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d=1.2√P
d=1.2√P 80 MHz to 800 MHz
d=2.3√P 800 MHz to 2.5 GHz
Where (P) is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and (d) is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey (a),
should be less than the compliance level in each
frequency range (b).
Interference may occur in the vicinity of equipment
marked with the following symbol.
